| Abstract: | The high temperature resistant repair coating was prepared by using epoxy resin and furan resin as matrix respectively,which was mixed with SiC powder and whisker.The ablative resistance property was investigated by using oxyacetylene ablation equipment.The materials and microstructures of the ablated samples were characterized by X-ray diffraction,energy dispersive spectroscopy and scanning electron microscopy.It is found that the furan resin/SiC coating with the mass ratio of SiC powder and whisker is 8/4... |
